Solie, D.N.Werdon, M.B.Newberry, R.J.Freeman, L.K.Lessard, R.R.2008Major-Oxide, Minor-Oxide, Trace-Element, and Geochemical Data from Rocks Collected in the Alaska Highway Corridor, Big Delta and Mount Hayes Quadrangles, Alaska in 2006 and 2007tabular digital dataRaw Data FileRDF 2008-2 v. 1.0.1Fairbanks, AK, USAState of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys23 pp.http://dx.doi.org/10.14509/16021Alaska Division of Geological & Geophysical Surveys (DGGS) personnel collected rock samples while mapping the bedrock geology along a 12-mile-wide swath following the Alaska Highway between Delta Junction and the eastern edge of the Mount Hayes quadrangle near Dot Lake, Alaska. This mapping is one component of the multi-year DGGS project studying the geology, geohazards and resources along the proposed gas pipeline corridor from Delta Junction to the Canadian border. In 2006, we collected 10 samples for whole rock (major- and minor-oxides, and petrogenetically important trace-elements) analysis. In 2007, we collected 111 samples for whole rock analysis and 36 rock samples for geochemical trace-element analysis. Analytical data from these rock samples are tabulated in this publication.The purpose of the overall project is to provide baseline information about geology, geohazards, and mineral and material resources along the proposed gas pipeline corridor. The data presented in this report are from rock samples collected during bedrock mapping in 2006 and 2007. The geochemical trace-element samples were chosen based on observation of anomalous physical characteristics that suggested possible enrichment in minerals of economic interest, or secondary characteristics associated with economic minerals. The rocks collected for whole-rock analyses were chosen from freshest samples available, to represent characteristic rock types in the map area or as representing rock types whose chemical composition can best characterize tectonic setting.
The data are available in tabular format as comma delimited ASCII files organized into six entities as described in this metadata file under the "Entity_and_Attribute_Information" section. The tables are as follows:

All trace-element geochemical analyses on rocks collected in 2007 were performed by ALS Chemex. Rock samples were crushed with a Terminator jaw crusher with chrome steel alloy plates so that at least 70 percent of the material passed through a 10 (2 mm) mesh screen. Representative aliquots of 250 grams and 30 grams each were taken using a stainless steel riffle splitter. These samples were then pulverized in a chrome steel ring mill so that 85 percent of the sample passed through a 200 (75 micron) mesh screen. Most trace-element analyses were performed on the 250 gram split while gold analyses were performed on the 30 gram representative split.
Samples were assayed for gold by gravimetric finish following a fire assay fusion (FA-GRAV). All other trace-element geochemical analyses were performed by inductively coupled plasma atomic emission spectroscopy (ICP-AES) methods following four-acid digestion. The elements that may be affected by incomplete digestion as well as analytical methods, and lower and upper detection limits are noted in Table 5.
All whole rock major- and minor-element analyses on samples from 2006 and 2007 were performed by ALS Chemex. Major- and minor-element oxides were determined by X-ray fluorescence spectrometry following a lithium metaborate fusion (LBF-XRF). Analysis of trace elements (Nb, Rb, Sr, Y, and Zr) in 2006 were performed by ALS Chemex, using wavelength-dispersive X-ray fluorescence spectrometry on pressed pellets (PP-XRF).
Trace element analyses on 2007 rock samples were performed by Dr. Rainer Newberry at the University of Alaska Fairbanks (UAF) Department of Geology and Geophysics. The analyses at UAF were conducted using wavelength-dispersive X-ray fluorescence spectrometry on pressed pellets using standard Norrish and Hutton (1969) procedures as described in Potts (1987) and as used by Cameron (2000). Well-calibrated international standards were used as a check of the analyses. The routine was customized for inter-elemental X-ray interferences in rocks of basaltic and felsic compositions. By comparing results on well-characterized rock standards, DGGS found in 2006 that the UAF routines yield more accurate trace element results and in 2007 we chose to perform the Nb, Rb, Sr, Y and Zr analyses using this procedure. Analytical methods and detection limits are tabulated in Table 6.
No topologic relationships are present in the data.This dataset contains all of the samples selected by DGGS for trace-element geochemical analyses and whole rock major oxide, minor oxide and selected trace element analysis in the Alaska Highway corridor between Delta Junction and Dot Lake during the summers of 2006 and 2007.Location data were downloaded from handheld Garmin GPS units (76C and 12XL) into an Access database.6A value of estimated position error in meters was calculate by the Garmin GPS units and recorded for each sample location. Estimated position error calculated by the Garmin units was not better than 3 meters and was less than 10 meters. The GPS system suffers from calculation and geometric error. This error results from items such as error in satellite positions, mathematical error introduced by the formulae used by the GPS unit for calculating position, and errors caused by narrow satellite alignments. Estimated position error is a value determined by the GPS manufacturer for the calculation and geometric error as a whole. "Selective availability", a deliberate degradation of GPS data managed by the U.S. government, was not operating during the time period these samples were collected.Field work: We carried out field studies from August 8 to August 15, 2006 and from July 9 to August 3, 2007. In 2006, we collected 10 samples for whole rock (major- and minor-oxides, and petrogenetically important trace-elements) analysis. In 2007, we collected 111 samples for whole rock analysis and 36 rock samples for geochemical trace-element analysis. ADGGS field personnel were Diana N. Solie, Melanie B. Werdon, Rainer J.

Potts (1987), Norrish and Hutton (1969), Cameron (2000)2007Update to text and Table 1: In the text on page 1, in the second paragraph under Analytical Methods, the digestion method for the ICP-AES analyses was changed from aqua regia to four-acid digestion. This change was also made to the Process Description for Laboratory work and Attribute_Accuracy_Report in this metadata. In Table 1, coordinates for samples 07LF543D and 07LF544c had been mistakenly switched and were corrected to the following: 07LF543D Lat (63.6404), Lon (-144.5477), UTM E (621468), UTM N (7059075) and 07LF544C Lat (63.6408), Lon (-144.5461), UTM E (621544), UTM N (7059128).
